Now I understand.. the park position wasn't set before using the park command..
According the documentation the 8407HC does only have two parking options depending on the side of pier it is at the moment of calling the park command. That's why I don't understand why it's possible to set a custom parking position (which is great and I need to test actually). How can I see release 2.9.0 is released?
Would it be possible to add a function for returning the mount to the home position (aka zero position) as well and the side of pier it is?
